In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the system, and the glass lenses may control the thermal effectand enlarge the space for arrangement of refractive power of the system.In addition, the opposite surfaces (object-side surface and image-sidesurface) of the first to the fifth lenses could be aspheric that canobtain more control parameters to reduce aberration. The number ofaspheric glass lenses could be less than the conventional sphericalglass lenses that is helpful for reduction of the height of the system.

When the lens has a convex surface, which means that the surface isconvex around a position, through which the optical axis passes, andwhen the lens has a concave surface, which means that the surface isconcave around a position, through which the optical axis passes.

The optical image capturing system of the present invention further isprovided with a diaphragm to increase image quality.

In the optical image capturing system, the diaphragm could be a frontdiaphragm or a middle diaphragm, wherein the front diaphragm is providedbetween the object and the first lens, and the middle is providedbetween the first lens and the image plane. The front diaphragm providesa long distance between an exit pupil of the system and the image plane,which allows more elements to be installed. The middle diaphragm couldenlarge a view angle of view of the system and increase the efficiencyof the image sensor. The middle diaphragm is helpful for size reductionand wide angle.

The optical image capturing system of the present invention could beapplied in dynamic focusing optical system. It is superior in correctionof aberration and high imaging quality so that it could be allied inlots of fields.
